Biography
Lorenzo was born on 12 September 1492, a son of Piero the Unfortunate and Alfonsina Orsini; he was the grandson of Lorenzo de Medici and Clarice Orsini. Niccolo Machiavelli was a friend of the younger Lorenzo, dedicating his work The Prince to help Lorenzo in being an effective Renaissance prince. In 1516, his uncle Pope Leo X made Lorenzo the Duke of Urbino after a costly war in which Lorenzo was founded by Francesco Maria I della Rovere. His mother arranged for Lorenzo to marry Madeleine de La Tour d'Auvergne, a French noblewoman, and his daughter would be Catherine de Medici, the regent of France during the French Wars of Religion. Lorenzo died of syphilis in 1519.
